Application filed. March 28, 191.6. Serial No. 87,325.

"To all "whom it may concern Be it known that l, HENRY E. BAST, a

citizen of the 'United States, residing at vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in vulcanizing devices.

The principal object of the invention is to provide a simple and cheap devicefor repairing rubber boots.

Another object is to provide a novel and ellicient device of this "character whereby any part of the sole and heel or upper can he quickly and easily vulcanized.-

Uther objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

1n the drawing: Figure 1 is a side elevation of improvedboot vulcanizer; Fig. 2 isa similar view showing a boot applied to the device and the parts in the position assumed -while the vulcanizing process is in progress; Fig. 3 is a top plan view of the device inthe position of Fig. 2; Fig. 4 is a transverse section on the line li of Fig. 8; Fig. 5 is a transverse section on the line 5 of Fig. 1; Fig. 6 is a side elevationshowing the device adjusted for vulcanizing the instep oi the boot; 1 1g. 7 1s a front elevation oi the device when used in vu l.caniz-' ins; the side of the boot.

Referring" particularly to the accompanyinp, drawing, 10 represents a vertical stand aid. the lower end of which is pivotally connected to an arm 171." by means of a bolt 12'", which arm is in turn pivotally adjustable on a clamp 11 by means of a clamping bolt 11. said clamp being; adapted to be engaged with the edge of the work bench 12. ()n the upper end of the standard is mounted a foot form or last '13. This last is adjustably mounted on the upper end of the standard so that it can be rotated to any desired position, both the last and the standard having the teeth 14, and the parts being held in adjusted positions by a screw l5, the upper end of which is countersunk into a recess 15' in the heel of the last.

Pivotally mounted on the lower end of the standard is an arm 16 adapted to swing in a plane at right angles to the standard and having a longitudinally extending slot v formed in. the outer portion thereof, as

shown at 17. This slot extends through the outer end of the arm for a purpose which will appear later. A nut 18 has 'grooves 19 formed in two of its opposite faces, and this nut is slipped into the slot 17 so that the side Walls of the slot enter the grooves of the nut. A set screw 20 is engaged through the nut, and carries dctachably on itsinner end a former block 21. is arranged to be pressed against the side of theboot 22 in the act of vulcanizing. The

outer face of the former block is provided This former block.

with a cui'rshaped recess 23 which is.

adapted to be filled with gasolene and-then lighted to produce the required amount of heat to accomplish the vulcanization. I

F or use in vulcanizing the sole and heel or the sides and top of the upper of the boot, I attach an angle plate 24 to the screw 20 by means of a nut 25, so that the angle plate can be turned on the screw to various angles. The outstanding portion of the angle plate is formed with a longitudinally extending and open-ended slot 26, in which is slidably disposed a nut similar in cmistruction to the beiore-uientioned nut, and carrying a set screw 1.8. This screw is adapted to carry a former block in the same manner as the lMFfOI'PrTHEHlLlODQCl screw.

What is claimed is:

l. A vulcanizing apparatus for boots comprising; an adjustably rotatable lasting jaclr for siu porting a boot, and a movably adjustaliile vulcanizing formerirnember carried by the jack. v

2. A ulcanizing apparatus for boots comprising an adjusta-bly rotatable lastinp jack, an arrn rotatably adjustable on the jack and a vuloanizing former block slidably and rotatably adjustable on the arm.

3. A vulcanizing apparatus for boots comprising; an adjustably rotatable lasting jack, a longitudinally slotted arm rotatably and adjustably mounted on the jack, and a vulcanizin former blocl; slidably and re tataloly adgustable in the slotted arm.

4. A vulcanizing apparatus for boots forcing the block against the rubber to be 'comprising an adjustably rotatable lasting vulcanized. 10
